PEGGlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 409,729, dated August27, 1889.

Application filed November 10, 1888- To all whom it may concern:

Be it known that I, JOHN E. BIoKEoRn, of lVhitman, in the county ofPlymouth and State of Massachusetts, have invented certain new anduseful Improvements in Pegging- Machines, of which the following, takenin connection with the accompanying drawings, is a specification.

, The object of my invention is to combine with that class ofpeggingmachine in which a supportinghorn is used a device for feedingthe horn along to correspond with the ordinary feeding device that workson the outer sole, and a device for cutting the pegs as they are driven.This object I attain by the mechanism shown in the'accompanyingdrawings, in which- Figure 1 is a front elevation of the upper part of apeggingnnachine with my improvement attached. Fig. 2 is ahorizontalsection taken on line a: m of Fig. 1. Fig. 3 is a front view of theupper part of a pegging-machine, showing some of the parts in sectionand some in elevation. Fig. 4 shows details in rear elevation. Figs. 5,6, and 7 are views which serve to illustrate the working of my device inconnection with the awl, driver, and feeding mechanism.

My invention consists in organizing and combining in one machine apegging mechanism, a feeding mechanism, a support for the shoe, and apeg-cutting mechanism, so that a shoe after being withdrawn from thelast can be pegged, including cutting the driven pegs, by the machine ina practical, rapid, and in all respects desirable manner. Heretoforethis has not been done, as there has been no device by which the innersurface of the leather could be supported while the pegs were beingdriven. The reason that no such support could be given is the fact thatthe hole in the horn was always in the same place, it being located on aline with the axis upon which the horn turned hence the hole had to beso large that the protruding point of the peg would have to have a'space to move in the diameter of which is as great as the largest feedmovement required, which is as great as one-fourth of an inch; and it isobvious that leather of the quality of which inner soles are made and ofthe temper in which inner soles are worked would Serial No. 290,481. (Nomodel.)

be totally unable to retain its place when not supported within aneighth of an inch of the point at which the peg penetrated it, and that,as actual practice has demonstrated, a shoe pegged on such asupport-that is, a support that has a hole one-fourth of an inch indiameter about the point of penetr.ationwill have an inner sole theinner surface of which will have on its peg-line a series ofprotuberances, which will prevent the pegcutter from working. In short,for this fact it has heretofore been impossible, or, atleast,impractical, to peg and cut the pegs on a machine, and therefore it hasnot been done. My machine admits of this being done, and in the mannerthat I will now explain.

In the drawings, A represents the frame of the machine, B the maindriving-shaft, and C the head of the machine.

In Fig. 3 I have shown a sketch of some of the working parts foroperating the awl E, peg-driver E, and feed mechanism D D; but I neednot enter into any description of these parts, as they are common topegging-machines, and form no part of my invention.

The supporting-horn H has a cylindrical extension H, (see Fig. 3,) whichforms a journal for it to turn on. The journal H fits in a sleeve of ahorizontal sliding piece H which is dovetailed into the top of theVerticallymoving housing HF, the housing I-I being connected by an arm HFigs. 1 and 2, to an upright slide 11 which slides vertically on adovetailed piece H bolted to the frame A. The housing H with its arm Hand upright slide H is moved up and down by a foot-lever, (not shown,)it being balanced in part by the counter-weight II on the lever H Thehorn H is moved vertically by the housing 1-1 and its connecting parts,as has been just set forth. This vertical motion is under the control ofthe operator, and is used in placing the shoe on the horn or in takingit off when pegged. The turning of the horn about its journal H is alsodirectly under the control of the operator, and is used for the purposeof presenting the different parts of the shoe to the pegging device.

In the drawings I have shown whatis called the band-feed device; but myinvention is equally adapted to work with an awl-feed device.

The parts and motions above referred to are old and in common use. I

I will now proceed to set forth the devices that I consider new and ofmy invention or directly connected to the same. The horn H has anopening 72, at the top, (see Figs. 3, 5, 6, and 7, (which is adapted toreceive in turn the end of the awl E and of the peg P, and as theopening h is but slightly larger than the awl, and as the awl does notmove in the sameline that the peg does, it is evident that the hole hmust either be large enough to extend from the field of motion of theawl to that of the peg and embrace both fields (and thus beobjectionably large) or the horn must move in the line of the feed, sothat the hole h will be in turn first directly under the line of motionof the awl, as shown in Fig. 5, and then (moving with the feed of theshoe) be directly under the peg, as shown in Fig. 6.

The device that I use for moving the horn H bodily in the same directionthat the shoe is moved by the feeding device consists of a cam-groove K,which, acting on a pin 70, (see Fig. 1,) gives motion to the lever K,pivoted at is. This lever K, acting through the link K and bent lever K(on pivot 75 link K and bent lever K (see Figs. 1, 2,3, and 4,) moves anarm H extending from the sliding sleeve H in which the journal II of thehorn H turns, and thus causes the sleeve H and its dovetail to move backor forth the distance v.between the awl and the peg, or, what is thesame thing, the distance from one peg to another. This movement of thehorn is timed so as to agree exactly with the feed-motion of themachine. Thus when the awl is in or about to enter the sole the horn isin the position shown in Fig. 5, and when the awl has been withdrawn andthe peg about to enter, or just entered, the horn is in the positionshown in Fig. 6. The horn remains in the position shown in Fig. 6 untilthe peg P is cut off, as shown in Fig. '7. Then it is returned by thecam-groove K and the levers, as above set forth, to the first positionshown in Fig. 5, ready for the next action. By thus causing the horn tomove with the feed-motion, instead of remaining stationary, as in theordinary machines, I facilitate the accurate feeding of the shoe as thework progresses, and save the inner sole of the shoe from being abradedor roughened.

I also have a great advantage in that class of pegging-machines in whichit is desirable to cut off the pegs as they are driven, for in thatcase, if the horn does not move with the feed, then the hole h must belarge enough to extend from the line of motion of the awl to the line ofmotion of the peg, thus presenting quite an opening over which the innersole has no support, and in case it is damp and (pivoted at D link Lbent lever L L (see Fig. 2,) link L bent lever L L, pivoted at L and thecam-groove L. The cutting action of the knife L (see Figs. 5, 6, and 7)takes place immediately after the peg has been driven and before thehorn has begun its backward movement, all of the parts being in theposition shown in Fig. 7, wherein the peg is represented as having justbeen cut, everything being ready for the horn to move back, so as tobring the hole h into the line of motion of the awl E.

To effect the adjustment of the throw of the horn, I can move thefulcrums of the levers K K K. The same adjustment may be eifected forthe peg cutting knife by changing the fulcrums of the levers L L.

It will'be observed that in my device all of that part of the horn thatserves as a support for the shoe, or is in contact with the shoe, moveswith and, in fact, forms a part of the feeding device. The peg-cuttersmove with the horn bodily when the feeding action is taking place, andmove in relation to the horn when acting to cut off the peg. In formermachines the horn is immovable, except about its own axis. In my machinethe horn has a lateral motion-that is, a feeding motionand in thisrespect is different from all other machines.
